What version of antechamber are you using? It sounds like a very old one,
since we have not used mopac for many years. If this is the case, you will
probably need to download the current version of AmberTools.

That said, 996 electrons with a net charge of -12 is a very large and unusual
molecule for antechamber. Are there ways you could break this molecule up
into segments?

....good luck...dac
